Optometric or ophthalmic practitioners are the doctors who mainly deals with various problems associated with eyes and imperfect vision. Medical science has achieved new heights of success in various treatments associated with vision and eyes.
Contact lenses are one of the most common treatments given by any optometrist for correction of vision of the patient. These lenses are basically a replica of our natural lenses used to improve the focus of our eyes. These lenses are supposed to rest on the cornea of our eyes just below the tear gland.
How do these lenses help?
Contact lenses have emerged as one of the most useful treatment for imperfect or blurry vision. These contact lenses rest on the cornea of the person. When a person blinks the eye, pressure of the eyelids keeps the lenses on place. Tears formed in the process of blinking helps in removal of any debris formed in the eyes and thus keeping the lenses clean. These lenses continuously stimulate the tear glands of a person and thus prevent any kind of drying, itchiness or scratching due to these lenses.
Different type of lens is made in treatment of different vision problem. Each person has an individual need and it can be satisfied by customising the lens for them. Some types of these lenses commonly used by the doctors are discussed below:
• Treatment of Astigmatism: Astigmatism is a vision problem in which contact lens has to be custom made for each and every patient. Optometrist is supposed to measure the cornea of the patient and make a lens accordingly. The lens given by the specific doctor should fit perfectly on the cornea and direct the entire light on one side of the cornea.
• Treatment of myopia: Myopia is also known as nearsightedness. It is a very common problem in many people. The lenses used in the treatment of myopia should be thin in the middle and thicker at the edges. This configuration of lenses helps the retina to process the light and thus help in correction of vision.
• Treatment of farsightedness: it is also one of the most common problems in people of all the age groups. Lenses used in this are just the opposite of what is used in myopia.
• Treatment of dryness of eyes: dry eyes have become a common problem due to over exposure of eyes to the screens. These lenses have proven to be the best solution in its treatment.
